Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the product described.Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/orproperty damage! Retain instructions for future reference.

DescriptionDayton Models 3VE48G, 3VE49G, 3VE50H, 3VE51H and 3VE52I heaters are 50,000 to210,000 BTU/Hr heaters. These heaters use 1-K Kerosene (see Operation section for alternative fuels) for combustion, and electricity to run the fan. It is primarilyintended for temporary heating of well ventilated buildings under construction,alteration, or repair. This heater may be used in agricultural, industrial and com-mercial environments.

However, #1/#2 diesel/fuel oil, JET A or JP-8 fuels may also be used if 1-K kerosene is notavailable. Be advised that these fuels do not burn as clean as 1-K kerosene, and care should be taken to provide more fresh air ventilation to accommodate any added contaminants that may be added to the heated space. Use any fuel other than 1-K kerosene may result in more periodic maintenance.

Operation (Continued)

NOTE: Kerosene should only be storedin a blue container that is clearly mark ed “kerosene”. Never store kero -sene in a red container. Red is associ -ated with gasoline.

- NEVER store kerosene in the livingspace. Kerosene should be stored in awell ventilated area outside the livingarea.

- NEVER use fuel such as gasoline,benzene, alcohol, white gas, campstove fuel, paint thinners, or other oilcompounds in this heater (THESE AREVOLATILE FUELS THAT CAN CAUSE AFIRE OR EXPLOSION).

- NEVER store kerosene in directsunlight or near a source of heat.

- NEVER use kerosene that has beenstored from one season to the next.Kerosene deteriorates over time. OLDKEROSENE WILL NOT BURN PROPERLYIN THIS HEATER.

- Use 1-K kerosene in this heater. #1/#2 diesel/fuel oil, JET A or JP-8 fuels are suitable substitutes.OVERVIEW OF HEATER DESIGN

Fuel System: This heater is equippedwith an electric air pump that forces airthrough the air line connected to thefuel intake, and then through a nozzlein the burner head. When air passes infront of the fuel intake, it causes fuel torise from the tank and into the burnernozzle.

This fuel and air mixture is then sprayedinto the combustion chamber in a fine mist.

SureFire Ignition: The electronic ignitorsends voltage to a specially designedspark plug. The spark plug ignites thefuel and air mixture described above.

The Air System: The heavy duty motorturns a fan that forces air into andaround the combustion chamber. Here,the air is heated and then forced outthe front of the heater.

THE SAFETY SYSTEM

Temperature Limit Control: This heateris equipped with a Temperature LimitControl designed to turn the heater offshould the internal temperature rise toan unsafe level. If this device activatesand turns your heater off, it may requireservice.

Once the temperature falls below thereset temperature, you will be able tostart your heater.

Electrical System Protection: Thisheater’s electrical system is protected by a fuse mounted to the PCB Assemblythat protects it and other electrical

components from damage. If yourheater fails to operate, check this fusefirst and replace as needed. Refer toSpecification chart on page 1.

Flame-Out Sensor: Utilizes a photocellto monitor the flame in burn chamberduring normal operation. It will causethe heater to shut off should the burnerflame extinguish.

FUELING YOUR HEATER

Never fill the heater fuel tank in theliving space: fill the tank outdoors.

Do not overfill your heater and be sureheater is level.

Never refill fuel tankwhen heater is

operating or still hot.

IMPORTANT: REGARDING FIRSTIGNITION OF HEATER. The first time you light the heater, it should be doneOUTDOORS. This allows the oils, etc.,used in manufacturing heater to beburned off outside.

Risk of indoor airpollution. Use heater

only in well ventilated areas.

Provide a fresh air opening of at leastthree (3) square feet (2,800 sq. cm) foreach 100,000 BTU/Hr. rating. Provideextra fresh air if more heaters are being used.

Example: A 3VE52I heater requires oneof the following :

1. A two-car garage door raised sixinches (15.24 cm).

2. A single-car garage door raised nineinches (22.86 cm).

3. Two, thirty inch (76.20 cm) windowsraised fifteen inches (38.1 cm).

TO START HEATER

4. 3VE48G model Only: Push powerswitch to “ON” position. Power Lampwill light and heater will start.

5. 3VE49G, 3VE50H, 3VE51H, and 3VE52I models: Turn thermostat control knobto desired setting and push powerswitch to “ON” position. Power lampwill light and heater will start.

NOTE: Room Temp. display indicates asfollowing:

- When room temp. is less than 0°F:“lo”.

- When room temp. is between 0°Fand 99°F: Indicates in figure.

- When room temp is less than 99°F:“Hi”.

If heater does not start, the thermostatsetting may be too low. TurnTHERMOSTAT CONTROL KNOB tohigher position to start heater. If heaterstill does not start, turn power switch to“OFF” and then to “ON” position (SeeFigure 10). If heater still does not start,see Troubleshooting on page 18.

NOTE: The major electrical componentsof this heater are protected by a safetyfuse mounted to the PCB board. If yourheater fails to start, check this fuse firstand replace as necessary. You shouldalso check your power source to insurethat proper voltage and frequency arebeing supplied to the heater.

TO SHUT DOWN HEATER

Turn switch to “OFF” and unplug powercord.

TO RESTART HEATER

1. Wait 10 seconds after stoppingheater.

2. Repeat steps under, “TO STARTHEATER.”

Shock Hazard!Always cover electric

outlet when not in use. Don’t plug anduse an appliance of more than 5Acurrent in this outlet.

LONG-TERM STORAGE OF YOURHEATER

FUEL TANK DRAIN

1. Drain fuel tank through fuel cap opening. (For Models 3VE48G, 3VE49G Only)2. Remove fuel drain bolt from rear bottom side of fuel tank using 3/4” socket or adjustable wrench and drain. (For Models 3VE50H 3VE51H, 3VE52I only)3. Using a small amount of kerosene, swirl and rinse the inside of the tank. NEVER mix water with the keroseneas it will cause rust inside the tank.Pour the kerosene out making sure that you remove it all.
